COTTON-SEED CRUSHER.

SPEGIFICAI'IQN forming part of Letters Patent No. 320,682, dated June23, 1885.

Application filed September 5, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, THEODORE A. PERRY, a citizen of the United States,residing at Plymouth, in the county of Washington and State of NorthCarolina, have invented certain new and useful Improvements inCotton-Seed Crushers; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being'had tothe annexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a side elevation of my invention,showing itattached to a cotton-gin. Fig. 2 is a cross-section of my i11- Ventionon an enlarged scale; Fig. 3, a top plan View thereof with the hopperremoved. Fig. 4 is a detail View in perspective of one of thesupporting-brackets; Fig. 5, a similar view of one of the adjustableboxes, and Fig. 6 a detail view in perspective of one of the scrapers.

The present invention has relation to certain new and usefulimprovements in that class of devices for cotton-gins wherein isemployed a pair of revolving rollers between which the seed passes as itcomes from the gin and is crushed.

The object of the invention is to improve the construction of the devicewhereby it is adapted for attachment to any of the cottongins in commonuse, or may be used independent thereof, as found desirable.

The invention therefore consists in the details of constructionsubstantially as shown in the drawings, and hereinafter described andclaimed.

In the accompanying drawings, A represents the hopper, arranged abovethe crushingrollers 13 C, said rollers having their hearings in boxesconnected to end-supporting brackets D. The roller 0 is made adjustable,so as to increase or diminish the space between it and the roller B,which I attain by the employment of boxes consisting each of the twosections E F, having slotted extensions a, through which pass suitablescrew-bolts, I), thus enabling the boxes of roller 0 to be set at therequired distance from the boxes of the opposite roller. This adjustmentof the roller is considered of importance in the class of de vices towhich my invention relates, as not only regulating the pressure on thecottonseed to crush either fine or coarsefor different grades offertilizer, which is frequently re- 5 quired, but the space between therollers may be increased to such extent as to allow the seed to passbetween them without being crushed, thereby obtaining the seed whole anduninjured when required for use in planting. The adjustment of theroller also enables the wearon the boxes and journals to be taken up.

It is evident that other means than those shown may be employed torender the roller adjustable without departing from the principle of myinvention,the means described,however, being considered the most simpleand practical.

Gear-wheels c d are connected to one end of the rollers B C, said wheelsbeing of different diameters, with a different number of teeth, thewheel 0 being smaller than the wheel 61, so that the rollers willrevolve at different velocities. This has a tendency to more perfectlyand effectually crush the seed than were the rollers revolving at equalrates of speed, as, instead of simply flattening the seed, they are tornto pieces as they pass between the rollers.

The brackets D, which support the boxes and rollers, are cast withflange-plates e f upon their inner sides, as shown more clearly in Fig.4, which are arranged at an acute angle to each other and haveperforations g, for securing thereto, by suitable rivets or bolts,boards G, which form the chutes for the discharge of the crushed seed.

The brackets D at their upper edges are each cast with semicircularbearings h, for the journals of the roller B, and seats i, for thesections F of the boxes for supporting the journals of the roller 0.

The inner vertical edges of the brackets D are cast withoutwardly-projecting clampingplates k, by which means the completecrushing attachment can be connected to the cottongin by suitableclamps, Z.

The scrapers consist of springs H,connected at their lower ends to theboards G, and at their upper ends have secured thereto longitudinalstrips of wood m,faced on their upper edges with metal, as shown at n.

The wooden strips m, as will be seen by ref ence to Fig. 2, bear againstthe peripheries of the rollers B O, and as they will wear away muchfaster than the metal faeingsn, they will. always leave sharp edges tothe facings, which will effectually remove from the surface of therollers any particles of seed adhering thereto. The strips of woodprevent the unequal wear of the metal facing,as they bear at all timesand with uniform pressure against the peripheries of the rollers, thesprings allowing the scrapers to yield in order to prevent too rapidwear; and the pressure on the rollers of the scrapers may be increasedor diminished by suit-able setscrews, p.

The rollers B C may be removed from their bearings and reversed to adaptthe attachment to a right or left hand gin.

One of the rollers may be provided with a suitable pulley for connectingwith the driving-belt of the gin, by which means the rollers arerevolved; or when the device does not form an attachment to the gin, butis used separately and independently thereof, any well-known means mayemployed for imparting to the rollers the required motion.

It will be seen that the device is complete in itself, and can be usedeither as an attachment to the gin or separately and independen'tlythereof.

The brackets D, which are cast with the plates 6 f k, are ready forattaching the boards G thereto, and are readily secured to the gin bysuitable clamps, these brackets being one of the essential features ofthe invention, and can be manufactured at a small cost.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. In a cotton-seed crusher, two revolving rollers, a discharge-chute,and a suitable hopper, in combination with suitable supporting bracketsfor said rollers, which are cast with flanges upon their inner sides,arranged, as shown, for attaching thereto the eh ate-boards, and attheir vertical'edges with outwardly projecting clamping-plates, forconnecting the crusher to the cotton-gin, substantially as and for thepurpose set forth.

2. In a cotton-seed crusher constructed substantially as described, thecombination, with the rollers and scrapers, consisting of flat springsprovided at their upper ends with wooden strips having their edgesmetal-faced, of suitable set-screws for regulating the pressure of thescrapers, substantially as and for the purpose described.

3. A cotton-seed crusher comprising a suitable hopper, two rollers,means for revolving them at different rates of speed, means for adjusting one of said rollers, brackets cast with fiangeplates andclamping-plates, the boards forming the chute, the clamps for thegin,and adjustable scrapers having at their upper ends wooden stripsmetal-faced at their edges, substantially as and for the purposespecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
